ABC News(OCALA, Fla.) -- Dee Dee Moore, the woman who was convicted of murdering Florida lottery winner Abraham Shakespeare, told ABC News' 20/20 in an exclusive interview from prison that she was not guilty and blamed her legal team for her guilty verdict.

"I would never harm another human being," Moore said. "I would never hurt nobody! I like Mickey Mouse and Donald Duck and Disney!"

Moore, 41, sat down for an interview with 20/20 in a cell block cafeteria at the Lowell Correctional Institute in Ocala, Fla., where she is serving a life sentence. Moore has maintained her innocence since the beginning of her trial last year.

On Dec. 10, 2012, Moore was found guilty of first degree murder and possessing and discharging a firearm after prosecutors argued that she swindled and then killed Shakespeare, 47.

Throughout the trial, Moore did not testify, and blamed her legal team for her conviction.

"I wanted my witnesses to take the stand," Moore said. "For me to take the stand, my lawyers said we didn't need it."

Jurors at Moore's trial took only three hours to deliver a guilty verdict, which Moore continues to contest.

"I think people are complete idiots that think I had anything to do with it," Moore told ABC News' 20/20. "I think they have no brain cells."

According to prosecutors, Moore allegedly befriended Shakespeare before he disappeared in 2009 after he had won $30 million in the Florida lottery three years earlier. By 2009, Shakespeare had used much of his winnings to pay off the mortgages of family and friends, often giving money away to people who simply asked for it. Moore had agreed to manage the little money he had left, but instead, prosecutors said, she stole his winnings and killed him.

According to authorities, Shakespeare was shot twice in the chest with a .38-caliber pistol in April 2009. He wasn't reported missing until November 2009, and his dead body was later found on Jan. 28, 2010, under a slab of cement after authorities spent days digging in the woods on a rural property in Plant City, Fla.
